my new chickens are not maken friends

Hi all just looking for some advice. I have 7 warren hens/battery hens and they all get on with each other.. But i have a 2month old chick that i have reared from birth (first of 6 to be integrated), and I have to keep her separate from the warrens because they all keep ganging up on her/pecking at her etc. Where I have her now, she can see them clearly and they can see her. I have kept her separate for about a week now, and the warrens all cluster up outside her little enclosure no matter what the weather! Is this normal behaviour, will they ever accept her? What do people think I should do?

Thanks!

yeah, Stuart's right - keep them separate for the time being.

It'll be hard when you integrate them anyway, because the oldies will feel like they're being upsurped.
